Abstract
Description
The present invention relates to a gooseneck for a die casting apparatus, and more particularly to a configuration for a gooseneck for a diecasting apparatus, in which a heater is detachably mounted, thereby making it possible to preheat the gooseneck before the molding operation by using a heater or torch temporarily. To a gooseneck for a hot chamber die casting apparatus having a detachable heater.
Generally, light metals are metals with a specific gravity smaller than that of titanium (specific gravity 4.5). Beryllium (specific gravity 1.85), magnesium (1.74), aluminum (2.7) and titanium (4.5) are typical examples. Among these, aluminum was the first to be put to practical use, and titanium was widely used as an aircraft material. Alkaline earth metals such as silicon (2.3), yttrium (4.3), alkali metals (1 or less) such as sodium, potassium and lithium and alkaline earth metals such as calcium (1.5) also enter the light metal from the point of view of small specific gravity, It refers to the four metals in the preceding example, which are materials.
Magnesium is the eighth most abundant element, accounting for 2.7% of the Earth's surface. Magnesium alloy has a specific gravity of 1.79 ~ 1.81, which is lightweight and has a weight reduction effect of around 70% of that of steel. It has been applied to a wide range of fields because it has excellent non-strength, castability, machinability, electromagnetic shielding ability, The use of which is increasing rapidly.
As a representative example of the light metal casting method, a die casting method is mainly used, and a die casting method includes a hot chamber, a cold chamber, and a thixomolding.
In the hot chamber type, an injection cylinder is installed in a melting furnace, and a high-temperature molten metal is pressurized so as to flow into a mold.
In the cold chamber type, a mold casting molding machine and a light metal melting furnace are individually constituted, and the melted molten metal is poured into an injection sleeve of a mold casting molding machine, and the molten metal is injected into the mold by an injection plunger.
The thixomolding method is a technology that combines the conventional injection molding method and metal die casting method and uses light metal raw material in chip form like resin injection.
1 and 2 are a perspective view and a side sectional view of a gooseneck according to the prior art.
As shown in the figure, the
Accordingly, the molten metal in the melting furnace is supplied to the cavity of the mold via the
On the other hand, the gooseneck requires work to preheat the work up to the working temperature before proceeding with a full-scale work of discharging the molten metal. In the case of the gooseneck according to the prior art, the gooseneck is heated by inserting the heater directly into the discharge port However, since the operation can not be performed until the heater inserted into the
In addition, since the body between the upper portion of the
Accordingly, it is an object of the present invention to provide an apparatus and a method for using a heater or a torch to temporarily preheat a gooseneck before a molding operation by using a detachable heater. The present invention provides a gooseneck for a hot chamber die casting apparatus having a detachable heater that enables rapid preheating without irrational and troublesome problems.
In order to accomplish the above object, a gooseneck for a hot chamber die casting apparatus having a detachable heater according to the technical idea of the present invention comprises a cylinder hole opened upward to reciprocate the piston therein, And a discharge port communicating with the cylinder hole and discharging the molten metal extruded by the piston toward the cavity of the metal mold; And a detachable member that is detachably attached to the nozzle portion formed with the ejection port and capable of interposing a heater between the nozzle portion and the gooseneck body when attached to the gooseneck body.
Here, the detachable member may be attached to and detached from the left side of the nozzle portion and the postal portion thereof, respectively.
In addition, the nozzle unit and the detachable member may have first and second insertion holes formed in the longitudinal direction in the vertical direction so that the heater can be inserted into the surfaces facing each other.
In addition, the detachable member may be attached to the nozzle unit by bolts.
The detachable member is made of a magnetic material and attached to the nozzle by magnetic force, and a plurality of insertion grooves and insertion protrusions corresponding to each other are provided on the surfaces of the detachable member and the nozzle portion facing each other .
The cylinder hole includes a lower cylinder hole in which a lower end portion of the piston reciprocates and a molten metal inlet port of the molten metal is formed, and an upper cylinder hole formed in a larger size on the upper portion of the lower cylinder hole, And may be formed in a shape that is not formed concentrically but biased toward the opposite side where the discharge port is formed.
The lower cylinder hole may have a smaller diameter in the lateral direction than a diameter in the forward and backward directions.
The gooseneck for a hot-chamber die casting apparatus according to the present invention is provided with a detachable heater, so that the preheating of the gooseneck before the molding operation can be quickly preheated without unreasonable troublesomeness such as using a heater or a torch temporarily.
Further, according to the present invention, since the thicknesses of the partition walls existing between the upper cylinder hole and the molten metal rising passage are increased by the eccentric structure of the upper cylinder hole and the upper cylinder hole, the crack prevention against the structural weak portion is effectively suppressed .
